7.5.
Although the Wi.232EUR module is very easy to use, care must be given to the design of the
power supply circuit. It is important for the power supply to be free of digital noise generated by
other parts of the application circuit, such as the RS-232 converter.
Figure 4 shows the schematic for our evaluation module circuit for the Wi.232EUR module. It
includes an on-board power supply and antenna connector. This evaluation circuit was used to
measure the performance of the Wi.232EUR module.
If noise is a problem, it can usually be eliminated by adding bypass capacitance or inductive
choking to the power supply, using a dedicated LDO regulator for the module, and/or by
separating the grounds for the module and the other circuits.

The UART interface is very simple; it is comprised of four CMOS compatible digital lines.
